Application filed November 30,1887- Serial No. 257,909. (No model.)

To aZZ whom it may concern: to be operated from the interior of the car, if Be it known that I, GEORGE H. BENJAMIN, desired. of the city, county, and State of New York, Arranged along each side of the car are the have invented certain new and useful Immain air-fines E, and extending inward to- 55 5 provements in Apparatus for Heating Railward the center of the car are the lateral airway-Cars, of which thefollowing is a specififlues F, preferably arranged as shown in the cation. plan, Fig. 2-that is to say, the lateral fiues My invention eomprehends the employment are arranged under alternate seats on opposite of steam derived from any suitablesource sides of the car.

P, arranged in the bottom of the flue L and In the drawings, A indicates a railwaycar, at a point lower than the base of the radiatorand B a steam-pipe, carried under the car or pipes G. IVithin this basket, which is pref- 9o within the car, its position not being mateerably made of wire and which is located in rial, and this pipe adapted to be connected a suitable vessel, Q, I place a quantity of any through suitable couplings between the cars material, preferably fibrous material, which with the source of steam. will serve to pick up the particles of dust in The pipe B, when two or more cars are conthe air and yet not interfere with the pas 95 5 nected, forms an unbroken passage for steam sage of the air to any extent. Fine-shaven throughout the entire length of the train, and wood, or what is known as excelsior, I find the steam employed in the several cars is carto be well adapted for the purpose. In pracried into and connected to the apparatus tice I find this material to give the best results within each through the medium of a pipewhen wet, and in order to provide for the I00 such as C-and in. this pipe I arrange a 0011- moisture of the material I arrange a pipe, R, trolling-valve, D, which valve maybe adapted under and communicating with the radiator G, and carry the condensed water from the radiator and discharge it through the sprinkler S over the material in the basket P.

In order to provide for any surplus of. condensed water, I arrange a waste-pipe, T, adapted to discharge under the car.

U represents an air-damper arranged in one end of the radiator-case, and which serves a double purpose,first, to allow the ingress of air from the floor of the car, and consequently at its lowest point when the car is at rest and but little air entering through the pipe L, and, secondly, to provide an opening through which the basket P may be removed in order to replace its filling, or for other purpose.

The operation of my device will be readily understood. When the car is in motion, the air enters through the hood M, passes downward through the pipe L over the material in the basket P, and thence upward, as heated, over the radiator-pipes D, ,and from the radiator by the pipe I to the main flue E, and thence through the lateral air-fines F outward to the interior of the car. If desired, the lateral flues may be provided with a damper, V, by which the air-exit from the lateral fl-ues may be closed,more or less, and thus cause the air to be equally'diffused throughout the car.

When a car is at rest, a much smaller proportion of air will enter through the pipe L than when the car is in motion, and the damper U may then be opened, as also the registers J or K, or both, as required.

I wish it understood that I do not limit myself to the various details of construction shown in the drawings and described in the specification, as many changes may be made therein without departing from the intent of my invention.

I claim as my invention 1. In a railroad-car, the combination of a pipe or diffusing air-flue within the car provided with lateral flues, a steanrradiator, a pipe for connecting said radiator with the source of steam, a casing for said radiator, with which the diffusing air-flue is connected, an air-induction pipe communicating with the external air and said casing, an air-filter for s rid induction-pipe, a pipe arranged to moisten the filter by the water condensed in the radiator, and a waste-pipe leading from the filter, substantially as set forth.

2. In a railroad-car, the combination of a pipe or diffusing air-flue within the car provided with lateral flues, a steam-radiator, a pipe for connecting said radiator with the source of steam, a casing for said radiator, with which the diitusing air-flue is connected, an air-induction pipe communicating with the external air and said casing, an air-filter for said induction pipe, a pipe arranged to in oisten the filter by the water condensed in the radiator, a waste-pipe leading from the filter, and an air-damper, U, in one end of the radiator for admitting air and for placing the filter-basket P, substantially as set forth.

.In witness whereof I have hereunto set my hand this 29th day of November, 1887.
